In order to determine if higher minimum wage leads to a higher unemployment two economic professors at Princeton University (David Card and Alan Krueger) conducted a study on minimum wage hikes with a focus on the New Jersey minimum wage hike in 1990. Card and Krueger compared unemployment and wages in New Jersey and Pennsylvania.
An increase in the minimum wage tends to have a âripple effectâ on other workers earning wages near that threshold. This ripple effect occurs when a raise in the minimum wage increases the wage received by workers earning slightly above the minimum wage. This effect of the statutory minimum wage on wages paid at the low end of the wage distribution more generally is well recognized in the academic literature.
